No progress, just stuck. Some suggestions are way beyond me i.e. LED flash - don't know what it is. So, helpless.

LED flash is beyond you? Where are you from, in case there is a language problem we have to overcome.

Flash or blink. Either action is what was asked of you. Led turns on, there’s a short delay, LED turns off, another short delay. Repeat forever. Program code to do this, connect an LED and resistor to the MCU and load the program.

 

For starters, get an STM32F4 Discovery board. It is well worth it.

Thanks. Got it. From Canada, so no lang. problem. I do have a programmer that is not called LED programmer, so was a tad confused. Wonder what is the next step.

 

Forget the LED programmer.

Get an STM32F407G-DISC1 or NUCLEO-G474RE.

 

Thanks. Actually I had bought a programmer ST-Link v2 for $ 20. Can't I use that instead?

You could but I don't know to what you are going to connect.

If you bought a genuine STM32 development board you can be up and running within minutes.

The Nucleo-G474RE is showing up for CAN$21.48.

This pic shows what it is connected to.

 

Fine. The next step would be to get STM32CubeIDE up and running and attempt to download a dummy shell program to your target MCU.
If you don't know how to do this I can take you through the steps.

 

Thanks. Yes, kindly take me through the steps.

 

Invoke STM32CubeIDE

Step 1 - Select New > STM32 Project




Step 2 - Target Selection > Select STM32G474VETx > Next



Step 3 - Enter Project Name > Finish



Step 4 - View Workspace > Core > Scr > main.c



Step 5 - Attempt to compile and run




Step 6 - Compiler runs. ST-LINK fails to connect.




Step 7 - Connect ST-LINK and try again. Click on Debug icon.



That's it.

If that works then you can go back and reconfigure your project in order to try a "Flash LED" test program.
